Scientific Method Review

What is a hypothesis?

• A proven fact that cannot be changed.

• A possible explanation of an observation that can be tested.

• A random guess without any basis.

• A conclusion drawn from multiple experiments.

What is an observation?

• The act of noticing and describing events or processes in a careful, orderly way.

• A method of collecting data through random sampling.

• A technique used to predict future events based on past data.

• The process of analyzing data to draw conclusions.

What is the importance of repeating experiments?

• To verify results and ensure accuracy.

• To make the experiment more complicated.

• To reduce the time taken for the experiment.

• To increase the number of variables involved.

What is the first step of the scientific method?

• Asking a question.

• Formulating a hypothesis.

• Conducting an experiment.

• Analyzing data.

What is a variable in an experiment?

• A constant that remains unchanged throughout the experiment.

• A factor that can change and affect the outcome.

• A measurement that is taken at the end of the experiment.

• A hypothesis that is tested during the experiment.

What should you do after conducting an experiment?

• Analyze your data

• Communicate your results.

• Discard your findings

• Repeat the experiment

What do you do when you decide if your data supports your hypothesis?

• You are drawing conclusions.

• You are collecting data.

• You are formulating a hypothesis.

• You are analyzing variables.

What is the purpose of an experiment?

• To test a hypothesis.

• To collect data without a specific goal.

• To prove a theory right or wrong.

• To observe natural phenomena without interference.

What is a control in an experiment?

• A variable that is changed during the experiment.

• A standard for comparison that remains unchanged.

• An observation made during the experiment.

• A hypothesis that is tested in the experiment.

What senses should you use when making an observation?

• Only sight and hearing

• Only sight, hearing, and touch

• You should use ALL 5 senses.

• Only smell and taste
